It sets my ancient sony 1080p TV to 24 fps when playing back 24 fps content.
On top of that, it let me recalibrate the colors using my iPhone camera.
Anyway, I bought it to reduce ad tracking, and was pleasantly surprised that it was roughly equivalent to buying a new TV.
What’s your setup like?
Right now I'm using the previous-generation AppleTV with a S/P-DIF output to drive the VSX-45TX, but Netflix has announced that they don't want to support that AppleTV model anymore, as of the end of July.
Sounds like the HDMI matrix box as mentioned by jmb99 is a likely win. There are a few models that break out the audio to S/P-DIF. Maybe by spending $99 instead of $19 I'll have better luck than I did with the simple audio extractor boxes I tried a couple of years ago.
Been there.
Now if the receiver is old enough to not have HDMI at all, there aren’t too many options. S/PDIF from the TV to the receiver works, but is lossy above 2 channels. HDMI audio extractors work, but most suck. I had a monoprice one for a few years that was decent, but not great. There aren’t any other options than that though, unless your sources have discrete channel outputs (an RCA jack for each channel), which these days are effectively non-existent.
